Using SkySafari 6 Plus (iPad Pro), to control the ETX90 via SkyFi and an AutoStar #497 controller, I can operate the telescope using the motion/direction arrows that are displayed on the SkySafari screen. When releasing the button, the telescope continues to slew, and there is no way of stopping this except for pressing a button in the opposite direction (at a slower rate in order to get it to come close to stationary). So, it is pretty unusable.
Ideas / suggestions welcome.
